Microsoft announced two new capabilities to enhance both virtualized server and virtualized desktop deployments:
Dynamic memory is an enhancement to Hyper-V R2 and allows IT administrators to pool all memory available on a physical host and dynamically distribute it to virtual machines running on that host as necessary. That means based on changes in workload, your VMs will be able to receive new memory allocations without a service interruption. More info: Dynamic Memory Coming To Hyper-V.
RemoteFX is a latest addition to Microsoft’s desktop virtualization stack. Using this new feature in Windows Server 2008 R2, you’ll be able to deliver an even richer and more user-transparent desktop virtualization experience. RemoteFX functions independently of any graphics stack and supports any screen content, including rich content like Silverlight or Flash. Because it uses virtualized graphics resources, RemoteFX works on a wide array of target devices, which means you can deploy it over both thick and thin client hosts and a wide variety of network configurations. RemoteFX will support certain OpenGL apps, and has been designed as a Windows Server capability to support growing demand for multi-user, media-rich centralized desktop environments. Windows 7 will be supported as a virtual guest OS under Hyper-V. More info: Explaining Microsoft RemoteFX.
